Creatine is noodle sprinter!

Author: Dr St├ęphane Cascua

Excerpt from "Food for athletes," Editions Amphora

The body does not lack of creatine

Creatine is naturally produced by the body and brought in sufficient quantities from food. The meat also take creatine for muscle contains animal too. Eggs, fish and dairy products are also used to make creatine. Indeed, the latter is formed from three amino acids used in the formation of proteins. Yet creatine supplementation is very popular in the sports speed and strength.

Creatine stores energy for sprints and jumps.

Creatine allows the synthesis of a substance rich in energy the "creatine phosphate" used directly by muscle fibers. This substance is readily available but very limited amount stored in the muscle, it allows a succession of violent contractions in less than 7 seconds. supplementation protocols were tested to try to increase reserves to extend the maximum speed phase during sprints or in order to multiply the acceleration in team sport. Unfortunately, these studies are not always rigorous. They show a small improvement in performance in athletes modest level. At the diligent athlete, it seems that the drive is sufficient to increase creatine phosphate stock. Body-builders use creatine as diluted in the muscle, it retains water and increases muscle volume.

Creatine supplementation is strongly discouraged

Anyway the "creatine" are prohibited for sale in France because its safety for health is not demonstrated. That answers the "precautionary principle". Possible side effects clearly outweigh the expected benefits. In high quantities, creatine can damage the kidneys and turn into a carcinogenic substance. In addition, the available online products have a particularly uncertain composition. Some providers do not hesitate to add cheap anabolic for increasing the apparent effectiveness of their products. This time, the risk to health is well documented and the competitive sports will be found positive in doping control!
